Intambo singabanjwa

Zonke iinyanga ezilithoba ukukhulelwa kamama nomntwana unodibaniso ngokusebenzisa imfesane yosana elandisiweyo ukususela eludongeni esiswini yosana olungekazalwa (kule ndawo, ukuba emva kokuzalwa kukuqulungana, ebizwa inkaba) kwaye ziqhotyoshelwe apha kule ngumkhaya. Intambo yosana i ntsontelo ngohlobo uwele olephuzayo bebumba amabini imithambo ndlela yosana. igazi lwemithambo mpilo kunye nezondlo olungekazalwa ukusuka ngumkhaya aqukuqela kwemithambo yosana. Xa umthambo ukusuka ngumkhaya ubuyela igazi ndingekazalwa, ahlanganiswe icarbon dioxide kunye neemveliso metabolic. Kunokwenzeka singabanjwa imfesane yosana kudala isoyikiso kubomi ezingekazalwa ngenxa mpilo ngxaki (hypoxia foetal). Emva ukunciphisa imfesane yosana ekuzalweni, yena uqala ukuphila ngokwahlukileyo ukusuka kumama wakhe. ukusika yokuqala intambo yosana (kwi imizuzwana embalwa yokuqala emva kokubeleka) kukhokelela kwilahleko igazi esimbaxa kunye ukuswela zesinyithi futhi umthamo egazini lweentsana.

Ikhusela iimpahla imfesane yosana (ukusuka naziphi na iimpembelelo eziyingozi kunye umonakalo) ezingqongileyo ijeli zabo ezizodwa ezifana eziphathekayo eziquka mucopolysaccharides waza wabiza ijeli Wharton kaThixo. imfesane yosana uvumela kuphela ukutshintshana emithanjeni negazi lwemithambo phakathi emzimbeni kamama kunye ndingekazalwa, kodwa ukwenza iintshukumo zakhe fluid, apho, ngenxa yezizathu ezahlukahlukeneyo, kunokuthi kwenzeke intambo singabanjwa. Ukuphuhlisa nomntwana, imfesane ukuya mzuzu lokuzalwa usana olungqamana ukwandisa ngokubanzi (avareji 55 cm) kwaye ububanzi enesiqingatha ubude ezimbini.

Kukho ukungaqheleki ezininzi imfesane yosana, akusoloko kusenzeka ukuba ukuseka ngoncedo ultrasound siswini. Uninzi lwazo ayicacanga kuze kwezidingo. Kuphela kwimeko monochorionic amawele (namawele afanayo, ukwabelana a ngumkhaya aqhelekileyo), udonga ongahlulwanga kunye previa ngumkhaya (kunye umngcipheko looding wayo) zingafumaneka kusengaphambili. Loo anomaly ezifana iintlobo intambo okanye azibophelele of ubungozi, obubonakala ngokuba yincwadi evuliweyo ezahlukeneyo iingxaki kwaye zifuna ukuziphatha ezithile ukuthintela okugula enxulumene nokufa.

ubude intambo ngenxa yezizathu ezingaziwayo ngo-5% yamatyala kunokuba ngaphantsi kwe-35 cm, yaye ngowe-5% ngaphezulu kwama-80 cm. Mfutshane iintambo enkabeni umda esaphula intshukumo intrauterine foetal kudaleke ingozi wona ngaphambi ngumkhaya. elide kakhulu enkabeni intambo okanye azibophelele igalelo ndingekazalwa, oko kukuthi uthambo azibophelele esinokubakho ngenxa ukuyilwa amaqhina okwenyaniso. Uthelekelelo ubude imfesane yosana prenatally (ngamanye amazwi, phambi kokuba unikezelo) akwenzeki. Kodwa kwiindawo okwenyaniso ngethuba lokukhulelwa kwakheka kwi imfesane yosana neziza ababuxoki. Kwiindawo okwenyaniso amele malunga ne-1% abakhulelweyo kunye onomlinganiselo ophezulu kumatyala kwamawele monochorionic. nodes False (bend kwi izitya imfesane yosana) ngakumbi ngokufanayo, kodwa kuyingozi olungekazalwa.

ibandla intambo ntiyiso kwenzeka ngenxa kwiintshukumo yosana olungekazalwa kwaye kungenzeka zokuphuhlisa nisaqala ukukhulelwa xa kukho isixa esikhulu noko ulwelo fluid (fluid), ngoko ke intshukumo olungekazalwa kakhulu ngakumbi. Umngcipheko ukubunjwa nodes okwenyaniso ixhomekeke ngqo kwi ubudala nonina, ubude imfesane yosana kunye nesixa fluid. stress rhoqo nokunyusa umgangatho adrenaline kwi uncedo egazini ukwandisa nokushukumisa olungekazalwa.

Kunokwenzeka intambo singabanjwa diagnoztsiruyut of hypoxia ezingekazalwa ngexesha uphando Cardiotocographic. Koko ukufunda echographic kuthwalelwa phandle, ubukho apho egqalwa ephambuka akhiwa imfesane yosana kummandla entanyeni. Kwakhona baphathe umbala Doppler isifundo kwaye bafunde intshukumo igazi ngokusebenzisa iimpahla. Ukuba ukrokrela ukuba hypoxia ezingekazalwa, ezi zifundo ziphindwa lonke lokukhulelwa amaxesha woomama ezininzi ngenxa intshukumo kwiindawo olungekazalwa ayikwazi lisenokubhidekisa kuphela, kodwa ukuqhekeka. Entwining imfesane yosana ekuzalweni ibangela bradycardia Palsy. Ukunciphisa ingozi yokuvumela esweni okokoko intliziyo ezingekazalwa, oku kwakhona kusetyenziswa ukukhawulezisa nokukhuthaza abasebenzi, yaye kwimeko kotyando likaxakeka yenzelwa phezu kwetafise utsalo okukhawulezileyo olungekazalwa - icandelo ngoqhaqho.
